High-Temperature, Ceramics-Based Composite Material

Japan Industrial Technology Association

Friday, 01 October 2010

This invention is a manufacturing process of a high-temperature, ceramics-based composite material that features excellent heat and oxidation resistance and frictional properties. The composite material is a dense SiC-infiltrated composite material, a dense carbon-fiber-reinforced SiC-infiltrated composite material, or a dense SiC-infiltrated composite material with granular carbon dispersed. The material is made by infiltrating molten carbon-silicide of Mo or a eutectic mixture of carbon-silicide and silicon carbide into a silicon-carbide-based preform, and then cooling and solidifying the melt.

The material has such a high oxidation resistance that it can be used in the atmosphere at 1,300 °C. or higher. Accordingly, this material can be used for areas that require high heat resistance and high mechanical strength and reliability, or where the target product may have a complicated shape.
